Parameters

Accessories

(1) Main torsion testing machine

(2) Sample clamps for different diameters

(3) Adjustable fixture supports

(4) Power cable and user manual

Test Procedures

(1) Secure the specimen between the two clamps.

(2) Set the torsion mode: unidirectional or bidirectional.

(3) Adjust the twisting speed and number of rotations as required.

(4) Start the test; for unidirectional torsion, the sample rotates 360° in one direction until the specified cycles or failure.

(5) For bidirectional torsion, the sample rotates 360° in one direction, then reverses for the same number of cycles until failure.

(6) Record torsion angle, torque, and failure data for analysis.

Maintenance Information

(1) Inspect clamps, fixtures, and moving parts regularly for wear or misalignment.

(2) Keep the machine clean and free from dust and debris.

(3) Check electrical connections and power supply stability.

(4) Lubricate rotating and moving components periodically as per manufacturer guidelines.

(5) Ensure calibration is maintained for accurate torque and angle measurements.

(6) Handle specimens and fixtures carefully to prevent damage to the machine or samples.
